Creates or updates a boop file to claim a directory for work. This signals that work is in progress and prevents other agents from working in the same directory.
AI agents use update_boop to create or update resources in Beep Boop MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Beep Boop MCP environment.
The tool performs a write operation by creating or updating a file to signal work-in-progress status. While it does affect coordination state (preventing other agents from working in the same directory), the action is reversible—the boop file can be removed or updated by other tools (such as end_work). This is coordination/state management rather than destructive action or code execution.
From the tool's definition Creates or updates a boop file to claim a directory for work. This is a reversible modification action that creates or updates data (a boop file) without permanent deletion.
Attacks that exploit this kind of access
Creates or updates a boop file to claim a directory for work. This signals that work is in progress and prevents other agents from working in the same directory. It is categorised as a Write tool in the Beep Boop MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Beep Boop MCP server in PolicyLayer and add a rule for update_boop: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Beep Boop MCP. Nothing to install.
update_boop is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_boop rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for update_boop. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
update_boop is provided by the Beep Boop MCP server (thesammykins/beep_boop_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
